Siemens BT300 - Startup Siemens Industry, Inc. • 3 1. SIEMENS BT300 - STARTUP 1.1 Startup Wizard In the Startup Wizard, you will be prompted for essential information needed by the drive so that it can start controlling your process. In the Wizard, you will need the following keypad buttons: Left/Right arrows. Use these to easily move between digits and decimals. Up/Down arrows. Use these to move between options in menu and to change value. OK button. Confirm selection with this button.

Practically every function that can be controlled by a digital input can also be controlled by a Time Channel. Instead of having an external PLC controlling a digital input you can program the "closed" and "opened" intervals of the input internally.

The pressure in the pipe will remain constant when we have no flow. However, with flow, the pressure will drop farther down in the pipe. This can be compensated by raising the setpoint as the flow increases. In this case, the flow is estimated by the output frequency and the setpoint is linearly increased with the flow as in the figure below.
